How it works

1. Activate Kiki-Jiki by tapping it, creating a token copy of Body Launderer with haste.
2. Activate Yahenni by sacrificing Kiki-Jiki.
3. When Kiki-Jiki dies, each Body Launderer's first ability triggers, causing them to each connive.
4. Resolve the Yahenni ability.
5. Activate Yahenni by sacrificing the token Body Launderer.
6. When the Body Launderer token dies, its second ability triggers, returning Kiki-Jiki from your graveyard to the battlefield.
7. Resolve the Yahenni ability.
8. Repeat.
